2. Stroke

According to the American Diabetes Association, people with T1D or T2D are 1.5 times more likely to have a stroke (also known as a brain attack). A stroke occurs when your brain stops receiving blood because of a clot in the neck or head.

Symptoms and signs of a brain attack include numbness in the face, leg, or arm; sudden weakness on one side of the body or face; dizziness; or trouble seeing with both eyes. If you start noticing any of these warning signs, seek medical help immediately. You may be referred to a stroke specialist, such as a neurologist.
